Definition of Fear of insects

Fear of insects: An abnormal and persistent fear of insects. Sufferers of this fear experience undue anxiety even though they realize that most insects pose no threat. To avoid insects, they may frequently clean rooms and carpets, sweep hallways, spray insect-killer or seal off doors and windows.

"Entomophobia" is derived from the Greek "entomos" (insect) and "phobos" (fear). The study of insects is called entomology.
